新型煤矿井下应急无线通信系统的建立

A wireless emergency communication system based on the Zigbee technology for modern mine

随着现代化煤矿的要求及无线通信技术的发展,地面无线通信技术(如PHS)开始应用于煤矿井下通信。通过分析基于Zigbee的短距离无线通信技术,提出了一种基于Zigbee技术的矿井应急救援无线通信系统,实现井下目标位置环境等参数远程采集,为救援决策提供科学依据。该系统基于S3C44B0X ARM7硬件平台和μC/OS-II软件平台开发出基于Zigbee技术的无线接力中继器来快速建立一条无线通信链路,并通过搭载环境参数传感器和红外摄像头的Zigbee前端实现对井下目标位置环境参数和视频图像的采集。重点介绍了该应急救援无线通信系统的原理、硬件组成和软件实现。

With the requirement of the modem mine and the development of the wireless technology, many wireless communication technology （e. g. PHS） has been introduced into the modem mine in recent years. In this paper, with a short description of cation system including the Zigbee repeater and the Zigbee Zigbee technology, a wireless emergency communicollection unit used to collect the environment parameter has been introduced. A wireless communication channel can be established rapidly by using the Zigbee repeater that is designed by using the S3C44BOX Arm7 processor and μC/OS-Ⅱ Operating System. The Zigbee collection unit can be used to get important information of the environment parameters and the field video. The data collected by environment sensors and the video by infrared camera can be transmitted to the central station via this system. The system hardware and software realization have been described too.
